When looking to upgrade the performance of your 6.7 Cummins, wouldn't you prefer something that installs easily AND delivers the power you're after? You can with the Stealth Mach 1! This turbo outflows the factory charger by 30% and can support up to 650 rear-wheel horsepower while maintaining all factory emissions.

The crown jewel of this turbo is a custom 11-blade compressor wheel that delivers a wide efficiency range and can drive 42-45 psi of boost. It is built from light weight, yet strong, billet 7075 aluminum and will aid in reducing or even eliminating turbo surge when towing. On the opposite end of the turbo, the turbine wheel has been upgraded, as well, to deliver a distinctive sound and provide better efficiency to reduce exhaust gas temperatures (EGT's) and reduce drive pressure when under load.

To properly match the entire turbo, a custom Calibrated Power exclusive vane-and-shroud plate assembly was produced, dubbed the Stealth Nozzle Ring. This was precisely matched to the larger turbine and gives the turbo a wider volute path for class leading load performance. This wider path was achieved via taller and wider vanes that are capable of extracting more energy from the turbine, literally sucking the air out of the engine faster than stock, which in turn drives the shaft faster to bring IN more cold air.

Finally, this is built from a brand-new turbo and genuine Holset electronics, meaning no core charge, and has been pre-calibrated, with no custom tuning required!

give this amazon basic option a try
Size: Standard (Pack of 2), Style: Soft, Configuration: Pillow
great comfort and value for everyday use. Designed with soft density, they provide gentle support that works well for stomach and back sleepers, helping maintain a comfortable sleeping position throughout the night. The down alternative fill feels plush yet lightweight, making the pillow cozy without being too firm. It holds its shape reasonably well and is suitable for guest rooms or daily use. While side sleepers may need more support, this pillow is a solid, affordable option for anyone looking for soft, breathable comfort.

COOL Pillowcases Worth Buying
Color: Champagne, Size: Queen
I bought these to try out, and I was shocked to find they worked out better than my silk pillowcases. I have atopic dermatitis, and I need a pillowcase that doesn't irritate my skin. I also am having hot flashes and need something cool on my face. These pillowcases are perfect for both my conditions. I plan to buy more in different colors. My sons and husband also like it since they are always hot.
